Stanford vs Columbia admissions

<p>From what i see, the admission rate for Columbia is the same, if not lower than that of Stanford.. But which is actually more selective? Are the applicants to Stanford in fact stronger, which makes it more selective even though its admission rate is wee bit higher?..</p>

<p>Do students who apply SCEA, since it's not ED, have an advantage compared to those who apply regular? What's the admission rate for SCEA?
thanks..</p>
